New to Oracle and .NET development? This video gives you everything you need to know to get up and running quickly!
We walk you through downloading and installing the needed Oracle software and then connecting in Visual Studio and creating a simple C# application.
The video starts at the Oracle .NET Developer Technology Center website at http://otn.oracle.com/dotnet
We then download the "ODTwithODAC" package, extract it and run the installer. Note that ODAC version 12 works with Oracle Database versions 10.2 or higher.
After installing we connect in Server Explorer and learn about the connection dialog features, including the Filters tab which by default filters out additional schemas you may have privileges on. We connect to the database using the easy to use EZ connect format.
Finally we create a simple C# application and connect to the database using ODP.NET Managed driver and a EZ Config connect string.
Prerequisites:
1) Visual Studio 2012 or 2013 -- any edition except Express Edition. Visual Studio Community Edition is supported.
2) An Oracle Database to connect to. You will need to know the hostname, port number and service name of the database.
During the video we install:
Oracle Data Provider for .NET
Oracle Developer Tools for Visual Studio
Oracle .NET Samples
Oracle .NET Documentation

BadImageFormatException Connect oracle database with visual studio .NET project with latest technology. If you are having BadImageException error or Architecture Mismatch error, this will be helpful more!

The controller responds to URL request, gets data from a model and hands it over to the view. The view then renders the data. Model can be entities or business objects.
In part 7, we have built Employee entity.
public class Employee
{
public int EmployeeId { get; set; }
public string Name { get; set; }
public string Gender { get; set; }
public string City { get; set; }
}
In this video, we will discuss, retrieving data from a database table tblEmployee using entity framework. In a later video, we will discuss using business objects as our model.
Step 1: Install entity framework, if you don't have it installed already on your computer. At the time of this recording the latest version is 5.0.0.0. Using nuget package manager, is the easiest way to install. A reference to EntityFramework.dll is automatically added.
Open visual studio - Tools - Library Package Manager - Manage NuGet Packages for Solution
Step 2: Add EmployeeContext.cs class file to the Models folder. Add the following "using" declaration.
using System.Data.Entity;
Copy & paste the following code in EmployeeContext.cs
public class EmployeeContext : DbContext
{
// Replace square brackets, with angular brackets
public DbSet[Employee] Employees {get; set;}
}
EmployeeContext class derives from DbContext class, and is responsible for establishing a connection to the database. So the next step, is to include connection string in web.config file.
Step 3: Add a connection string, to the web.config file, in the root directory.
Step 4: Map "Employee" model class to the database table, tblEmployee using "Table" attribute as shown below.
[Table("tblEmployee")]
public class Employee
{
public int EmployeeId { get; set; }
public string Name { get; set; }
public string Gender { get; set; }
public string City { get; set; }
}
Note: "Table" attribute is present in "System.ComponentModel.DataAnnotations.Schema" namespace.
Step 5: Make the changes to "Details()" action method in "EmployeeController" as shown below.
public ActionResult Details(int id)
{
EmployeeContext employeeContext = new EmployeeContext();
Employee employee = employeeContext.Employees.Single(x =] x.EmployeeId == id);
return View(employee);
}
Step 6: Finally, copy and paste the following code in Application_Start() function, in Global.asax file. Database class is present "in System.Data.Entity" namespace. Existing databases do not need, database initializer so it can be turned off.
Database.SetInitializer[MVCDemo.Models.EmployeeContext](null);
That's it, run the application and notice that the relevant employee details are displayed as expected.

Selecting Which Data Access Components (DAC) to Use with RAD Studio XE7
Lachlan Gemmell
CodeRage 9 - Object Pascal Track
Tuesday, October 28, 2014 - 4pm Pacific Time
FireDAC, DataSnap, dbExpress, IBX and dbGo are all options available out of the box to Delphi/C++ Buider programmers. Faced with these choices how should you make the decision on which database access layer to use in your applications. Some of the factors that may influence your decision can include: 1) Ability to connect to particular database servers, 2) Support for server side database server features, 3) Component interfaces and style of programming required and 4) Support for advanced client side features. We'll take an overview look at all the different database technologies that come with XE7 and discuss how they compare in these regards and others.

HOW TO CREATE LINKED SERVER AND HOW TO QUERY ORACLE DATABASE FROM SQL SERVER MANAGEMENT STUDIO.
SQL server 2017 makes it easy to configure linked server.
You can use open-query to get or manipulate data of linked server database.
CONFIGURATION SUMMARY:
PROVIDER : oracle provider for oledb.
DATA SOURCE : It is usually a combination of oracle server IP: port number/t.n.s listener name.
e.g. 192.168.1.10:5121/orcl
OPEN QUERY : select * form openquery(linked_server_name, ' sql query statement ')
Configure a linked server to enable the SQL Server Database Engine to execute commands against OLE DB data sources outside of the instance of SQL Server. Typically linked servers are configured to enable the Database Engine to execute a Transact-SQL statement that includes tables in another instance of SQL Server, or another database product such as Oracle. Many types OLE DB data sources can be configured as linked servers, including Microsoft Access and Excel. Linked servers offer the following advantages:
• The ability to access data from outside of SQL Server.
• The ability to issue distributed queries, updates, commands, and transactions on heterogeneous data sources across the enterprise.
• The ability to address diverse data sources similarly.
An oracle linked server require OLE DB provider.
An OLE DB provider is a DLL that manages and interacts with a specific data source.
If your oracle database is not in same server then you have to install The Oracle Data Access Components (ODAC) for Windows consists of Oracle client side drivers.
An OLE DB data source identifies the specific database that can be accessed through OLE DB. Although data sources queried through linked server definitions are ordinarily databases, OLE DB providers exist for a variety of files and file formats. These include text files, spreadsheet data, and the results of full-text content searches.
Typically, linked servers are used to handle distributed queries. When a client application executes a distributed query through a linked server, SQL Server parses the command and sends requests to OLE DB. The row set request may be in the form of executing a query against the provider or opening a base table from the provider.

In this video, we will learn about what is the concept of 2 tire architecture and create the data access layer how to insert or save and show record from sql server database using using connection oriented method.

Meet members of the .NET teams at Oracle and Microsoft to learn about Oracle’s new ADO.NET provider for .NET Core (currently in beta), discuss future plans for Oracle support on EF Core, and more. We will have demos and answer questions from the audience.

This video will show you How to fix "MSVCR100.dll missing from your computer" error which comes for various application when you try to run the application like Visual studio 2008, 2010 or 2012, wamp or php server, some popular games etc. Follow the steps that i have showed in this video. For that i have used the following link to download MSVCR100.dll file. Use this link to download the dll file

This video walks through the configuration of msmdpump.dll, which allows users to connect to SSAS Multidimensional or Tabular instances using HTTP or HTTPS.
This configuration is typically used to enable secure connections from Internet/Extranet users to Analysis Services cubes or Tabular models. Users can use any client that supports the standard OLEDB driver, for example Microsoft Excel.

An introduction to using FireDAC and the Data Explorer in the RAD Studio, Delphi and C++Builder IDE to connect to Oracle Database Server. Uses the TFDConnection, TFDMongoQuery to retrieve data and LiveBindings to bind the data to the user interface controls.

Typhoon is a comprehensive and reliable application that was developed to assist you in managing the contents of your Oracle databases, enabling you to add, edit or remove tables without needing to resort to SQL statements to get the job done.
To gain access to the utility, you first need to create an account using a preferred set of credentials, which will then be required to enter every time you wish to work with Typhoon.
The program allows you to connect to a local or cloud server, by providing the necessary information, including name, version, driver and service ID. You can also input the network details, specifically the host and port number, along with the username and password, or even the database URL. Prior to saving the configuration, you can test the connection to make sure everything is in order.
Once you connect to the Oracle database, Typhoon allows you to view its contents, namely the tables that it comprises. You can browse through them, select a record and update it. Similarly, you can add a new one, as the tool enables you to ‘Insert Number Data’, ‘Insert Blob Data’, ‘Insert Clob Data’, ‘Insert String Data’ or ‘Insert Date Data’.
Moreover, you can create a new table by defining the number of columns that you need, assigning it a name, then filling out the columns and rows with the information you wish it to store. All of this can be done without having to resort to SQL statements or commands. Other options include the ability to drop tables from the database.
This Java-based utility also offers you a series of SQL 'Syntax References', (statements and functions) and which you can analyze in detail, to learn how to better work with them, then use them for your own purposes.

There is a really good open source C++ libary to do this through ODBC. It is easy to set up and showcase. I demo this briefly on it.
